1 Claim. -(o1. 257-125) which is such in construction that it permits access to be had to tubes in the core assembly for cleaning purposes.

It is a matter of common knowledge that there are at least three well-known and generally accepted methods of cleaning automobile radiators. For example, there is the so-called reverse flush procedure utilizing water under pressure, but it has been my experience that this is a hit or miss method and is not usually successful. Secondly, there is the generally described boiling out method which, in my judgment, is superior to the reverse flush procedure, but here again, it has been my experience that the stated second method is not as efficient as is generally claimed by radiator repairmen. The best-known method is that wherein the accumulations in the core tubes are rammed or pushed out by roding same. It is the consensus of opinion that the latter method is best suited for ordinary purposes but requires considerable laborious effort and time and necessitates the workman melting the top tank or header from the core tubes and subsequently, replacing same. There is another objection and that is the roding method makes it necessary to take the radiator oil of the car and the expense attached to a complete successful job is often considerable.

The purpose of the present invention is to so construct the header that the cover or top section is removable, whereupon it exposes the upper open ends of the tubes and permits same to be plunged out with the usual rod means.

In carrying out the invention, I provide a sectional header, the lower section constituting a base and being of receptacle form and rigidly secured to the upper open ends of the tubes and the cover section being latched or otherwise connected to the first section and the two sections being properly joined together for fluid-tight coaction.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings:

Figure 1 is a perspective view of a sectional header, constructed in accordance with the principles of the present invention.

Figure 2 is a rear elevational view of same.

Figure 3 is an end view observing Figure 2 from either end.

Figure 4 is a horizontal section on the plane of g I e the line 4-4 of Figure 2, looking in the direction of the arrows.

Figure 5 is a cross-section, on an enlarged scale, on the line 5-5 of Figure 2, looking in the direction of the arrows.

Reference is had first to Figure 5, wherein the core or tube assembly is denoted by the numeral 1, the same being made up of conventional-type vertical tubes 8, open at opposite ends. The improved sectional header is denoted by the numeral 9 and comprises a receptacle-like base section I0, which is secured to the upper ends of the tubes, the latter projecting into the section In, in the manner shown. The upper edges of the walls of said section III are fashioned into an endless V-shaped adapter flange H. The upper complemental section of the header constitutes a cover and is denoted by the numeral l2, and is a rectangular shell which is open at its bottom. The lower ends of the walls forming said shell are fashioned into beads l3 and the latter are seated removably in the channel provided by said flange H. In practice, a suitable sealing compound or gasket means is provided (not shown) to insure an effective liquid-tight seal between parts II and I3. Also, a neck is provided on the rear side, as at M, to accommodate the customary circulating hose (not shown). The top of the shell is provided with a filler neck l5 and closing cap l6.

Suitable means is provided for releasably latching the sections 10 and [2 together. I prefer the means shown in the drawings comprising a plate I! rigidly secured to an end of the base section and provided with a keeper hook l8, to accommodate a link l9 forming a part of a toggle-type latch. The bail portion of the latch is indicated at 20 and the two parts are hingedly connected in the manner shown, and the arms of the bail are hingedly mounted on cars provided on a foundation plate 2|, secured to the end of the upper cover section I2. This sort of latching means provides the necessary take-up 38017101! and insures proper mating relation of the upper and lower sections 12 and M respectively.

I next call attention to the strainer screen 22, which is preferably provided, and is seated on supporting pins, or the like, 23 provided in the base section I 0.

It is evident that with the construction shown, the latches may be readily released and the sections 10 and I I disconnected, the section l2 being bodily removed. Then, the screen 22 is lifted out and access is had to the upper open ends of the core tubes 8. Thus exposed, the tubes may be readily cleansed and scaled under the aforementioned roding method.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression practice so long as no departure is made from,,.

the invention as claimed.

Having described the invention what-islclaimed as new is:
